ASSA Locker Hasps for Padlock-Operated Lockers

ASSA locker hasps provide a mechanical locking point for a separate padlock. They are suitable for compatible lockers, cabinets and storage doors in schools, workplaces, leisure centres and changing rooms.

Two principal sizes are available: short ASSA locker hasps for doors up to 16 mm thick and the longer ASSA 492831 for doors up to 22 mm thick. Both use a rotating rear catch, allowing suitable lockers to be secured without issuing an individual built-in lock key.

Choose by door thickness first. The correct fitting also depends on the existing mounting aperture, turning direction, rear catch and intended padlock. See the Specification section for detailed installation requirements.

Handing and ordering: The product selector on this page distinguishes door thickness, not turning direction. Right-hand operation is the manufacturer's standard arrangement. Left-hand versions are available within the ASSA range but must be confirmed separately before ordering. Do not assume that changing the door-thickness selection also changes handing.

Other short ASSA hasp designs include models 390785 and 390684. These are alternative designs within the manufacturer's range, not additional options in the current door-thickness selector.

How ASSA Padlock Hasps Work

With the padlock removed, the hasp and rear catch can turn through 90° to release or secure the locker door. Once a suitable padlock is fitted, the hasp cannot rotate and the catch remains engaged.

Users can provide a compatible key-operated or combination padlock. This reduces the need to issue integrated locker keys, although facilities may still need procedures for lost padlock keys, abandoned padlocks and locker access.

Choosing a Padlock for an ASSA Locker Hasp

Choose a padlock that matches the selected hasp's shackle opening and available clearance. ASSA recommends 5–7 mm shackles for its short locker hasps and 5–8 mm for the longer 492831 design, with at least 19 mm of internal shackle opening.

Check that the complete padlock body can close without fouling the locker door or neighbouring compartments.

Browse our locker padlocks for suitable key-operated and combination options.

Locker Compatibility and Replacement Applications

ASSA padlock hasps can be used on compatible metal, timber, laminate and composite locker doors. Applications include new padlock-operated installations and selected conversions from existing cam locks or coin locks.

A matching door aperture alone does not guarantee compatibility. Rear catch engagement, door thickness, handing and frame clearance must also be suitable.

For replacement work, compare the existing fitting with the manufacturer drawings in the Specification section before ordering.

ASSA Hasps for Leisure and Changing-Room Lockers

Padlock-operated hasps are used in leisure centres, sports facilities, gyms, schools and staff changing rooms. They provide a straightforward mechanical locking arrangement without batteries, wiring or an integrated user key.

Suitability for swimming-pool environments and other humid or chemically cleaned locations depends on the exact hasp, catch, fixings and padlock materials. Confirm corrosion resistance and cleaning compatibility before installation.

For complete installations, explore our swimming-pool lockers and leisure and changing-room locker ranges.

ASSA Locker Hasp Fitting and Installation

ASSA locker hasps are available for different door thicknesses and locking arrangements. Use the model comparison in the Features section and the manufacturer specification sheets above to identify the appropriate fitting before ordering.

Door Preparation and Fitting Requirements

The listed ASSA hasps use an 18 × 22 mm double-D door preparation. The shaped opening helps prevent the hasp body from rotating in the door. Check the existing opening rather than assuming that all ASSA locker locks use identical fittings.

Door thickness: Choose a model suitable for the actual door thickness, up to 16 mm or 22 mm as applicable.
Mounting aperture: Check the 18 × 22 mm double-D cut-out and any existing fixing hardware.
Handing: Confirm the required right- or left-hand operation against the available product variant.
Catch: Check its length, offset, orientation, fixing and engagement behind the locker frame.
Padlock: Confirm the permitted shackle diameter and at least 19 mm of internal clearance where specified.
Door clearance: Ensure that the hasp and padlock can operate without interfering with the door, frame or neighbouring lockers.

Choosing the Correct ASSA Catch

The rear catch must engage correctly with the locker frame. A matching door aperture alone does not guarantee compatibility, especially when replacing an older lock or converting from a keyed or coin-operated mechanism.

Measure the existing catch and check whether it is flat, stepped or offset. The correct catch may need to be selected separately from the hasp body.

View available components in our ASSA locker catches and cam arms range.

Replacing Cam Locks and Coin Locks

Some existing ASSA cam locks and coin locks can be converted to padlock operation where their door preparation, thickness and rear catch arrangement are compatible with the replacement hasp.

On timber or laminate locker doors with round mounting holes, a suitable conversion or reinforcement plate may be required to form and support the double-D opening. Confirm the door's suitability before altering the aperture.

For larger refurbishment projects, test one replacement fitting with its intended catch and padlock before ordering quantities for an entire locker installation.

Ordering Replacement ASSA Locker Hasps

For identification or bulk replacement enquiries, provide the existing product number if known, door thickness, front and rear photographs, mounting-hole measurements, catch dimensions, handing and required quantity.

For help identifying a suitable replacement, contact Total Locker Service. You can also compare our locker hasp lock range or browse ASSA replacement locks and fittings.

Frequently Asked Questions About ASSA Locker Hasps

What is the difference between 16 mm and 22 mm ASSA locker hasps?

Short ASSA hasps, including models 391350, 390785 and 390684, are specified for doors up to 16 mm thick. The longer ASSA 492831 is specified for doors up to 22 mm thick. Door preparation, handing and catch compatibility must also be checked.

What size padlock fits an ASSA locker hasp?

The listed short ASSA hasps specify 5–7 mm padlock shackles, while the 492831 model is listed with a 5–8 mm shackle range. Allow at least 19 mm of internal shackle clearance and confirm the selected model's specification before ordering.

What door opening is required for an ASSA locker hasp?

The listed fittings use an 18 × 22 mm double-D opening. Existing apertures, door thickness and fixing arrangements must be checked before installation. Conversion plates may be required for some doors.

Are right- and left-hand ASSA locker hasps available?

Right- and left-hand arrangements are available within the ASSA hasp range. Confirm the required turning direction and the exact product variant supplied, as handing may differ between models.

Is the rear catch supplied with the ASSA hasp?

Catch selection depends on the particular fitting and the product supplied. A separate catch may be required to suit the locker frame. Check the product listing and compare the existing catch with the available ASSA cam arms.

Can an ASSA locker hasp replace a keyed or coin-operated lock?

Some keyed and coin-operated locker locks can be converted to a compatible ASSA padlock hasp. Check the mounting aperture, door thickness, handing and rear catch. A matching hole alone does not guarantee that the conversion will work.
